Basic Terminology...................................................................... 26

1.1 Overview
This section describes the main components of F-Secure Client Security
and F-Secure Policy Manager and provides an introduction to policy
based management.
1.2 F-Secure Client Security Components and
Features
F-Secure Client Security is used for protecting the computer against
viruses, worms, spyware, rootkits and other malware, and against
unauthorized access from the network. F-Secure Client Security consists
of Virus Protection, Internet Shield, and Application Management. When
installing F-Secure Client Security, you can select which of these
components are installed.
1.2.1 Virus and Spy Protection
Virus and Spy Protection includes several scanning methods: Real-Time
Scanning, E-mail Scanning, Web Traffic Scanning, Rootkit Scanning, and
Manual Scanning. It also includes System Control, Automatic Updates,
the F-Secure Automatic Update Agent and the Virus News service.
Real-Time Scanning
The Real-Time Scanning feature gives you continuous protection against
viruses and spyware as files are opened, copied, moved, renamed and
downloaded from the Web.
Real-Time Scanning functions transparently in the background, looking
for viruses whenever you access files on the hard disk, diskettes, or
network drives. If you try to access an infected file, Real-Time Scanning
will automatically stop the virus from executing. It will then either remove it
from the file or display a warning, as specified in the security policy. For
more information, see “Configuring Real-Time Scanning”, 166.
CHAPTER 1 19
E-mail Scanning
E-mail Scanning can be used for scanning both incoming and outgoing
e-mail messages and attachments. It prevents viruses from getting inside
the company network and it also prevents you from accidentally sending
infected attachments outside. E-mail Scanning can be configured to drop
infected attachments from incoming e-mails. When it has found an
infection in an outgoing e-mail, it can block the outgoing e-mail traffic until
the problem has been solved. For more information, see “Configuring
E-mail Scanning”, 173.
Web Traffic (HTTP) Scanning
Web Traffic Scanning protects computers against viruses in HTTP traffic.
It scans HTML files, image files, downloaded applications and executable
files, and removes viruses automatically. For more information, see
“Configuring Web Traffic (HTTP) Scanning”, 178.
Rootkit Scanning
If you want to ensure there are no suspicious hidden files, hidden
processes, hidden applications or hidden drives in your computer, you
can scan the system manually for rootkits. For more information, see
“Configuring Rootkit Scanning”, 172.
Manual Scanning
You can use Manual Scanning, for example, after you have installed
F-Secure Client Security, if you suspect that there might be a virus or
spyware on the computer, or if a virus has been found in the local area
network. You can select whether all files or only a certain types of files are
scanned. You can also decide what action to take with an infected file, the
Disinfection Wizard will guide you through the process. You can also use
the Scheduled Scanning feature to scan your computer automatically
and regularly, for example weekly or 1-2 times a month.
20
System Control
System Control is a new, host-based intrusion prevention system that
analyzes the behavior of files and programs. It provides an extra-layer of
protection by blocking undiscovered viruses, worms, and other malicious
code that try to perform harmful actions on your computer. For more
information, see “Configuring System Control”, 171.
Automatic Updates
The Automatic Updates feature keeps the virus and spyware definitions
always up-to-date. The virus definitions updates are signed by F-Secure
Anti-Virus Research Team. The signature is based on strong encryption
and the packet cannot be altered in transit.
In case of complex viruses the virus definitions updates include removal
tools that are executable binaries. The integrity of the delivered
executable code is very important, and F-Secure scanning engines check
that all update code is signed by F-Secure Anti-Virus Research. If the
integrity is compromised, the code will not be executed. For more
information, see “Configuring Automatic Updates”, 162.
F-Secure Automatic Update Agent
With F-Secure Automatic Update Agent, you are able to receive virus
definition updates and informational content without interrupting your
work to wait for files to download from the Web. F-Secure Automatic
Update Agent downloads files automatically in the background using
bandwidth not being used by other Internet applications, so you can
always be sure they will have the latest updates without having to search
the Web.
If the F-Secure Automatic Update Agent is always connected to the
Internet, it will automatically receive new virus definition updates after
they have been published by F-Secure.
When the F-Secure Automatic Update Agent service is started, it
connects to F-Secure’s Automatic Update Server. The agent will keep
polling the server regularly to see whether there is new content available.
The agent downloads only the parts of virus definitions that have changed
/
